WebAlternatively, as shown in FIG. 8, the desired sample beam can be achieved simply by exploiting the fact that in an SBC grating, a small percentage of spurious beams are diffracted at the 0 th order. Thus, in lieu of a separate beam splitter or DOE sampling grating, the N spurious 0 th orders of SBC grating 67 may be captured as sample beams 68. struggle is a never ending process
